"Mankind was my business. The common welfare was my business" Marley S1
Marley's ghost, burdened by chains, is a tragic figure unable to achieve redemption. This is the first warning towards scrooge; If he doesn't change he will end up like Marley.
The repetition of "business" contrasts his earlier focus on material gain with the moral and social obligations he failed to fulfil.
"Are there no prisons? Are there no workhouses?" Scrooge S1
Dickens condemns the Victorian reliance on workhouses, which were notorious for their inhumane conditions.
Scrooge's rhetorical questions show his indifference to the plight of the poor, suggesting he views them as burdens rather than individuals deserving compassion.
"Spirit, tell me if Tiny Tim will live." S3
Scrooge’s growing worry for Tiny Tim shows the first signs of his transformation. He starts to understand the value of human life.
This contrasts with scrooge's earlier disregard for others and failure to empathise with those whose situations are far different from his; "If he be like to die, he had better do it and decrease the surplus population"
"I am as light as a feather, I am as happy as an angel, I am as merry as a schoolboy." S5
symbolizes his freedom from the burden of greed and loneliness
Comparing himself to an angel suggests his moral redemption, while being “merry as a schoolboy” highlights his youthful excitement.
